A system and method are provided for protecting data information stored in a storage medium. The system includes a memory unit which is divided into a plurality of storage regions in which data information is stored; a domain unit which includes a plurality of OS domains, which are access subjects, and loads the data information stored in the storage regions that are accessed by the OS domains; and a control unit which controls access of the domain unit to the memory unit.
摘要:
A wireless universal serial bus (WUSB) security is provided. A method of providing a session key to be used during a session between a host and a device creates the session key based on a seed key stored in a region that is not allowed by the device; and provides the session key to the device. Therefore, a user does not need to distribute information necessary for creating the session key(i.e., a connection context) to a guest device.

A method and an apparatus for transmitting a message to a plurality of wireless devices that are classified into units of groups are provided. The method includes operations of: (a) determining whether the message is a predetermined message for detecting a device in a network; (b) encrypting the message with one of a plurality of keys respectively corresponding to a plurality of groups according to a determination result obtained in operation (a), each group comprising one or more devices in the network; and (c) transmitting the encrypted message. Accordingly, it is possible to prevent a guest wireless device that is unknown to a user from detecting a home wireless device of the user and controlling the detected home wireless device without authorization from the user.

An apparatus and method are provided for safely switching among security consoles and acquiring ownership with respect to a controlled device by executing an electronic signature using a smart card. An apparatus for executing a security function using a smart card includes: a smart card read unit which acquires a public key of a security console by reading the smart card; an authentication unit which verifies validity of an electronic signature transmitted from the smart card by using the public key of the security console; and a switching unit which switches the apparatus to a security console capable of acquiring ownership with respect to a controlled device if the electronic signature is determined to be valid.
摘要:
Provided is a mode-based access control method that includes: making a security mode list which indicates security setting states of devices existing in a home network; setting a specific security mode selected from the modes on the security mode list; and making the devices perform functions thereof in the specific security mode. Also, provided is a mode-based access control device includes: an authentication unit which checks information on a user and authenticates the user; a mode configuration unit which makes a security mode list indicating the security setting state of devices forming a home network; a mode setting unit which sets a specific security mode selected from modes on the security mode list; and an operating unit which causes the devices to perform functions thereof in the specific security mode.
